My biggest concern (length) was addressed, and I am very happy with the news.
It only makes sense to follow up arguably the shortest Zelda title (TWW) with the longest.
Was TWW the shortest? I seem to remember the 2d zeldas being shorter, but w/e. TWW had too much 'filler' content in it for me as it was, I'd rather prefer a shorter, more focused adventure than an 80 hour fetch quest.
So yeah, that is a very big difference versus the 3:4 interlaced gamecube version. I think this might be the best launch game in history. =D
4:3 progressive scan gamecube version, thank you very much.
Oh, and I think I'd give Halo or Super Mario 64 the title of best launch game, and Super Smash Bros Melee if you'll extend launch to mean within the first couple weeks of launch.
